What is LUW?
Ans Logical Unit of Work
Different types of LUWs. What r
they?
Ans Two types of LUW are:
1) DB LUW - A database LUW is the mechanism
used by the database to ensure that its data is always consistent. A database
LUW is an inseparable sequence of database operations that ends with a database
commit. The database LUW is either fully executed by the database system or not
at all. Once a database LUW has been successfully executed, the database will
be in a consistent state. If an error occurs within a database LUW, all of the
database changes since the beginning of the database LUW are reversed. This
leaves the database in the state it had before the transaction started.
2) SAP LUW - A logical unit consisting of
dialog steps, whose changes are written to the database in a single database
LUW is called an SAP LUW. Unlike a database LUW, an SAP LUW can span several
dialog steps, and be executed using a series of different work processes.

CALL SCREEN 1000.

What are the differences between
SAP memory and ABAP memory?
Ans ABAP Memory is a memory area in the
internal session (roll area) of an ABAP program. Data within this area is
retained within a sequence of program calls, allowing you to pass data between
programs that call one another. It is also possible to pass data between
sessions using SAP Memory.
SAP Memory
is a memory area to which all sessions within a SAPgui have access. You can use
SAP memory either to pass data from one program to another within a session (as
with ABAP memory) or to pass data from one session to another.
What are differences between At
selection-screen and At selection-screen output?
Ans AT SELECTION-SCREEN event is triggered in
the PAI of the selection screen once the ABAP runtime environment has passed
all of the input data from the selection screen to the ABAP program.
AT
SELECTION-SCREEN OUTPUT - This event block allows you to modify the selection
screen directly before it is displayed.
What are the events?
What is get cursor field?
Ans GET
CURSOR statement transfers the name of the screen element on which the cursor

LENGTH <len>].

What is the difference between
occurs 1 and occurs 2?
Ans
What is the difference between Free
and Refresh?
Ans Free - You can use FREE to initialize an
internal table and release its memory space without first using the REFRESH or
CLEAR statement. Like REFRESH, FREE works on the table body, not on the table
work area. After a FREE statement, you can address the internal table again. It
still occupies the amount of memory required for its header (currently 256
bytes). When you refill the table, the system has to allocate new memory space
to the lines.
Refresh -
This always applies to the body of the table. As with the CLEAR statement, the
memory used by the table before you initialized it remains allocated. To
release the memory space, use the statement
What are elements?

What are tables?
Ans Tables : ZREKHA_EMP.
It creates
a structure – the table work area in a program for the database tables, views
or structure ZREKHA_EMP. The table work area has the same name as the object
for which we created it. ZREKHA_EMP must be declared in the ABAP dictionary.
The name and sequence of fields in the table work area ZREKHA_EMP corresponds
exactly to the sequence of fields in the database table, view definition in the
ABAP dictionary.
What are client-dependant tables
and independent tables?
How to distinguish client-dependant
tables from independent tables?
What is the use of Table
maintenance allowed?
Ans Mark the Table maintenance allowed flag
if users with the corresponding authorization may change the data in the table
using the Data Browser (Transaction SE16). If the data in the table should only
be maintained with programs or with the table view maintenance transaction
(Transaction SM30), you should not set the flag.
